Lates calcarifer is one of the main marine foodfish cultured in Singapore along with tilapia, milkfish, golden snapper (Lutjanus spp.) and estuarine grouper (Epinephelus tauvina) [15]. The development of sea cages intensified during mid 1981 when the government implemented a marine foodfish farming scheme to encourage people to set up floating farms in designated coastal areas along Northern parts of Singapore. In 1985, the total aquaculture production of L. calcarifer valued S$1.8 million, accounting 13% in terms quantity and 20% in terms of value [15]. The total production was 1284 tonnes in 1985 and around 4147 tonnes in 2011, accounting to 0.6% of the world’s production (Figure 7). Currently, we have fish farms in areas like the northern parts of Singapore, off Pasir Ris and southern parts of Singapore (e,g Palau Semakau) and even land-based closed aquaculture system which allows extensive water quality control by SIF technologies.
